Flash NUCLEO-H743 with UART in CubeProgrammer

[MZoto.1]

I have NUCLEO-H743 board. After I load the firmware with this pin configuration, the board began to give an error STLINK (PB4 is NJTRST). Initially, the board was flashed even with this configuration, but after Debugging it stopped. I was advised to use UART, but I found no information on how to do this on boards with H7, only for older boards. Where do I need to connect the pins on the board to make the firmware possible?

Hi @MZoto.1​ ,

Sorry for the delay.

Before using UART can you please try to connect via STLink with mode "under reset" or  with "Power Down Mode" ?

If still not working and you want to use UART , you need to drive the BOOT0 in your board.

How to drive the BOOT0 and Hardware connection required are available in NUCLEO-H743  User manual .

Hope it helps you .
